2
Scarcity and the Factors of Production
What is economics? How do economists define scarcity? What are the three factors of production?
3
What Is Economics? Economics is the study of how people make choices to satisfy their wants For example: You must choose how to spend your time Businesses must choose how many people to hire
4
Scarcity and Shortages
Scarcity occurs when there are limited quantities of resources to meet unlimited needs or desires Shortages occur when producers will not or cannot offer goods or services at current prices
5
The Factors of Production
Land All natural resources that are used to produce goods and services. Labor Any effort a person devotes to a task for which that person is paid. Capital Any human-made resource that is used to create other goods and services.

The Factors of Popcorn Production
Land Popping Corn Vegetable Oil Labor The human effort needed to pop the corn Capital Corn-Popping Device

Section 1 Assessment 1. What is the difference between a shortage and scarcity? (a) A shortage can be temporary or long-term, but scarcity always exists. (b) A shortage results from rising prices; a scarcity results from falling prices. (c) A shortage is a lack of all goods and services; a scarcity concerns a single item. (d) There is no real difference between a shortage and a scarcity. 2. Which of the following is an example of using physical capital to save time and money? (a) hiring more workers to do a job (b) building extra space in a factory to simplify production (c) switching from oil to coal to make production cheaper (d) lowering workers’ wages to increase profits Want to connect to the PHSchool.com link for this section?

Opportunity Cost Does every decision you make involve trade-offs?
How can a decision-making grid help you identify the opportunity cost of a decision? How will thinking at the margin affect decisions you make?
10
Trade-offs and Opportunity Cost
Trade-offs are all the alternatives that we give up whenever we choose one course of action over others. The most desirable alternative given up as a result of a decision is known as opportunity cost. All individuals and groups of people make decisions that involve trade-offs.
11
The Decision-Making Grid
Economists encourage us to consider the benefits and costs of our decisions. Benefits being with the most beautiful girl at school getting his first date seeing many beautiful girls on the beach Experiencing new things Decision go to prom go to cali Opportunity cost Benefits forgone more dates possible relationship Personal satisfaction getting a tan seeing a movie star good seafood Go to Prom Cali Trip with all his friend Alternatives Conner’s Decision-making Grid
12
Thinking at the Margin When you decide how much more or less to do, you are thinking at the margin. Options 1st hour of extra study time 2nd hour of extra study time 3rd hour of extra study time Benefit Grade of C on test Grade of B on test Grade of B+ on test Opportunity Cost 1 hour of sleep 2 hours of sleep 3 hours of sleep
13
Section 2 Assessment 1. Opportunity cost is
(a) any alternative we sacrifice when we make a decision. (b) all of the alternatives we sacrifice when we make a decision. (c) the most desirable alternative given up as a result of a decision. (d) the least desirable alternative given up as a result of a decision. 2. Economists use the phrase “guns or butter” to describe the fact that (a) a person can spend extra money either on sports equipment or food. (b) a person must decide whether to manufacture guns or butter. (c) a nation must decide whether to produce more or less military or consumer goods. (d) a government can buy unlimited military and civilian goods if it is rich enough. Want to connect to the PHSchool.com link for this section? Click Here!

Production Possibilities Graphs
What is a production possibilities graph? How do production possibilities graphs show efficiency, growth, and cost? Why are production possibilities frontiers curved lines?
16
Production Possibilities
A production possibilities graph shows alternative ways that an economy can use its resources. The production possibilities frontier is the line that shows the maximum possible output for that economy. Watermelons (millions of tons) Shoes (millions of pairs) 25 20 15 10 5 Production Possibilities Graph a (0,15) 15 8 14 b (8,14) 14 18 20 21 12 9 5 A production possibilities frontier c (14,12) d (18,9) e (20,5) f (21,0)

Efficiency Efficiency means using resources in such a way as to maximize the production of goods and services. An economy producing output levels on the production possibilities frontier is operating efficiently. Shoes (millions of pairs) 25 20 15 10 5 Watermelons (millions of tons) Production Possibilities Graph c (14,12) d (18,9) e (20,5) f (21,0) a (0,15) b (8,14) S g (5,8) A point of underutilization

Growth Growth If more resources become available, or if technology improves, an economy can increase its level of output and grow. When this happens, the entire production possibilities curve “shifts to the right.” Shoes (millions of pairs) 25 20 15 10 5 Watermelons (millions of tons) Production Possibilities Graph T Future production Possibilities frontier c (14,12) d (18,9) e (20,5) f (21,0) a (0,15) b (8,14) S

Cost Cost A production possibilities graph shows the cost of producing more of one item. To move from point c to point d on this graph has a cost of 3 million pairs of shoes.

Section 3 Assessment 1. A production possibilities frontier shows
(a) farm goods and factory goods produced by an economy. (b) the maximum possible output of an economy. (c) the minimum possible output of an economy. (d) underutilization of resources. 2. An economy that is using its resources to produce the maximum number of goods and services is described as (a) efficient. (b) underutilized. (c) growing. (d) trading off.

Answering the Three Economic Questions
What key economic questions must every society answer? What basic economic goals do societies have? What types of economic systems exist today?
23
The Three Economic Questions
Every society must answer three questions: What goods and services should be produced? How should these goods and services be produced? Who consumes these goods and services?
24
Economic Goals Societies answer the three economic questions based on their values. Economic Goals Making the most of resources Economic efficiency Freedom from government intervention in the production and distribution of goods and services Economic freedom Assurance that goods and services will be available, payments will be made on time, and a safety net will protect individuals in times of economic disaster Economic security and predictability Fair distribution of wealth Economic equity Innovation leads to economic growth, and economic growth leads to a higher standard of living. Economic growth and innovation Societies pursue additional goals, such as environmental protection. Other goals

In a free market economy, households and business firms use markets to exchange money and products. Households own the factors of production and consume goods and services. monetary flow physical flow Circular Flow Diagram of a Market Economy Households Firms Households pay firms for goods and services.
